Grab this 6-pack of Motorcraft SP-580-X iridium spark plugs.

They’re brand new, OEM quality, and made in Japan.

Cross-reference number CYFS-12-YT4X if you’re matching to factory specs.
These are direct replacements for many Ford applications—smooth idle, better mileage, and reliable starts.
Iridium construction means they last longer than standard plugs too.

Prop 65 warning for nickel, but that’s standard for pretty much any plug these days.

Packaged new, ready to ship fast.
Whether you’re a DIYer or a pro, these plugs are a solid choice.
